| Abstract: | The influence of local strain on the electromechanical coupling characteristics of a structural system with closely-located sensors and actuators is investigated numerically using ANSYS and experimentally using a cantilever beam bounded with two piezoelectric patches.The local strain is analyzed and the generation factors are studied.Finally,the experiment confirms the local strain. |

| Keywords: | piezoelectric element local strain collocated control self-sensing |
